BACKGROUND AND OBJECTIVES: Kale is a rich source of provitamin A- β-carotene. This study used intrinsically labeled kale [2H9] β-carotene to determine the effect of peanut butter on the bioconversion of kale β-carotene to vitamin A in preschool children. METHODS AND STUDY DESIGN: Preschool children (n=37; age 12-36 mo) were randomly assigned to 50 g cooked kale (1.5 mg β-carotene content) with either 33 g peanut butter (PBG) or with 16 g lard (LG) and a reference dose of 1 mg [13C10] retinyl acetate capsule...

BACKGROUND: Recent trials have shown that avoiding peanuts during infancy increases the risk of peanut allergy; however, these studies did not address maternal peanut consumption. OBJECTIVE: We sought to investigate the relationship between maternal peanut consumption while breast-feeding, timing of direct peanut introduction, and peanut sensitization at age 7 years. METHODS: Secondary analysis of a nested cohort within the 1995 Canadian Asthma Primary Prevention Study intervention study was performed...

PURPOSE OF REVIEW: In the past decade, food allergy has been increasingly recognized as an important public health issue. The role of maternal and infant diet in the development of food allergy has been a major focus of research throughout this period. Recently, research in this area has moved from observational studies to intervention trials, and the findings from these trials have started to influence infant feeding guidelines. In this article, we review recent studies of dietary interventions for preventing food allergy, summarize current knowledge and discuss future research directions...

Peanut (Arachis hypogaea L.) is an important oilseed and cash crop worldwide. Wild Arachis spp. are potental sources of novel genes for the genetic improvement of cultivated peanut. Understanding the genetic relationships with cultivated peanut is important for the efficient use of wild species in breeding programmes. However, for this genus, only a few genetic resources have been explored so far. In this study, new chloroplast genomic resources have been developed for the genus Arachis based on whole chloroplast genomes from seven species that were sequenced using next-generation sequencing technologies...

Stilbenes are a class of polyphenolic compounds, naturally found in a wide variety of dietary sources such as grapes, berries, peanuts, red wine, and some medicinal plants. There are several well-known stilbenes including trans-resveratrol, pterostilbene, and 3'-hydroxypterostilbene. The core chemical structure of stilbene compounds is 1,2-diphenylethylene. Recently, stilbenes have attracted extensive attention and interest due to their wide range of health-beneficial effects such as anti-inflammation, -carcinogenic, -diabetes, and -dyslipidemia activities...

BACKGROUND: Little is known on the clinical relevance of peanut 2S albumin Ara h 7. OBJECTIVE: To investigate the discriminative ability of Ara h 7 in peanut allergy and assess the role of cross-reactivity between Ara h 2, 6 and Ara h 7 isoforms. METHODS: Sensitization to recombinant peanut storage proteins Ara h 1, 2, 3, 6 and 7 was assessed using a line blot in sera from 40 peanut tolerant and 40 peanut allergic patients, based on food challenge outcome...

The role of immunization in the production of antibodies directed against immunogens is widely appreciated in laboratory animals and in humans. However, the role of immunization in the development of "natural antibodies" has not been investigated. Natural antibodies are those antibodies present without known history of infection or immunization, and react to a wide range of targets, including "cryptic" self-antigens that are exposed upon cell death. In this study, the ability of immunization to elicit the production of natural antibodies in laboratory rats was evaluated...

REVIEW
Victor Turcanu, Helen A Brough, George Du Toit, Ru-Xin Foong, Tom Marrs, Alexandra F Santos, Gideon Lack
The environmental factors driving the increase in food allergies are unclear and possibly involve dual exposure to allergens, microbiome-driven effects or other mechanisms. Until they can be better understood, early intervention aiming at establishing oral tolerance provides an effective way to decrease the window-of-risk when children may develop allergic sensitisation to foods due to the absence of a protective immune response. Thus, the recent LEAP (Learning Early About Peanut allergy) and LEAP-On studies achieved a high level of peanut allergy prevention by early introduction of peanuts in the infants diet and conveyed more information regarding the evolution of IgE and IgG4 antibody responses to food antigens over time...

BACKGROUND: Although previous single-center studies report the rate of anaphylaxis for oral food challenges (OFCs) as 9% to 11%, little is known regarding the epidemiology of clinical OFCs across multiple centers in the United States. OBJECTIVE: To examine the epidemiology, symptoms, and treatment of clinical low-risk OFCs in the nonresearch setting. METHODS: Data were obtained from 2008 to 2013 through a physician survey in 5 food allergy centers geographically distributed across the United States...

Black peanut skins as a byproduct from peanut industry contain abundant anthocyanins, evaluated as 8.61±0.27mg/g dry black peanut skins, are currently poorly exploited. In this work, four anthocyanins and three major flavonols were detected and identified by HPLC-PDA-ESI-MS/MS from the acidified water extract of black peanut skins of Arachis hypogaea L. After preliminary removal of flavonols by ethyl acetate (EtOAc), further purification of the anthocyanins was conducted using a combination of Amberlite XAD-7HP and ODS-AQ-HG column chromatography methods Two most abundant monomeric anthocyanins cyanidin-3-O-sophoroside (5...

AIM: Globally, rates of paediatric food-induced anaphylaxis (FIA) are increasing. Little data is available regarding the epidemiology of FIA among New Zealand (NZ) children. This study investigated the incidence of paediatric (0-14 years) FIA hospital presentations in NZ over a 10-year period. METHODS: Ministry of Health public hospital discharge data from 2006 to 2015 were analysed using FIA-related International Classification of Diseases codes (T78.0 - anaphylactic shock due to adverse food reaction and T78...

Selecting suitable plants tolerant to heavy metals and producing products of economic value may be a key factor in promoting the practical application of phytoremediation polluted soils. The aim of this study is to further understand the utilization and remediation of seriously contaminated agricultural soil. In a one-year field experiment, we grew oilseed rape over the winter and then subsequently sunflowers, peanuts and sesame after the first harvest. This three rotation system produced high yields of dry biomass; the oilseed rape-sunflower, oilseed rape-peanut and oilseed rape-sesame rotation allowed us to extract 458...

The Individual Healthcare Plan (IHP) was implemented in schools in France in 2003 to improve management of allergic children. Our objectives were to assess the practical aspects of IHP (excluding asthma) and allergic reactions occurring at school. METHODS: Prospective study conducted in the North Department (France) during the 2015/2016 school-year. Two questionnaires were developed: one for the school doctors (n=67) and one for the school principals (n=2372). RESULTS: Data from 336 (25%) of the 1325 IHPs (0...

Purpose: Sigma 1 Receptor (Sig1R) is a novel therapeutic target in neurodegenerative diseases, including retinal disease. Sig1R-/- mice have late-onset retinal degeneration with ganglion cell loss that worsens under stress. Whether Sig1R plays a role in maintaining other retinal neurons is unknown, but was investigated here using rd10 mice, a model of severe photoreceptor degeneration. Methods: Wild-type, rd10, and rd10/Sig1R-/- mice were subjected to ERG and spectral-domain optical coherence tomography (SD-OCT) to assess visual function/structure in situ...

The embryonic leaflets of peanut (Arachis hypogaea) variety Huayu 20 were used as explants and pingyangmycin as a mutagen to induce somatic embryos. Four weeks after the inoculation, the survived explants were transferred to somatic embryo germination medium containing screening reagent hydroxyproline, and finally 15 regenerated plants were obtained. Pedigree breeding method was used during the following selection breeding, and three lines with significantly increased yield and 23 lines with high oil content were obtained from these mutant offsprings...
